ASoC: dt-bindings: qcom: add LPASS LPR vote clock ID

Browse Source 
Add a new clock ID, LPASS_HW_LPR_VOTE, to represent the LPASS low-power
resource (LPR) vote through the PRM interface.

The LPASS PRM supports a resource voting mechanism to control low-power
states via PARAM_ID_RSC_CPU_LPR. Exposing this as a q6prm clock ID allows
clients to request the LPR vote using the existing qcom,q6prm clock
provider interface.

This functionality is required on newer platforms (e.g. Hawi) where LPASS
clients need to explicitly manage LPR resource voting via PRM.
